MTC CCCH Group Segmentation for Wireless Congestion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Machine-type communication (MTC) devices in GERAN wireless communication systems generate traffic congestion, which can degrade services for existing human-to-human communication devices, necessitating an efficient method to manage resource allocation based on traffic characteristics and network congestion.
Innovation Solution
A data transmission method for MTC devices that involves receiving CCCH configuration information, selecting an MTC CCCH group based on specific parameters, and allocating the MTC CCCH to specific time slots, allowing for efficient congestion control by separating MTC traffic from human-to-human traffic, thereby minimizing the impact on existing services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If MTC devices are deployed in GERAN, then data communication capability is improved, but traffic load on the network increases causing congestion
Solution Approach 1:
The patent segments the CCCH resources into separate groups: normal CCCH groups for human-to-human communication devices and MTC-specific CCCH groups for machine-type communication devices. This segmentation allows MTC devices to access dedicated resources, improving their data communication capability while preventing them from contributing to congestion on shared resources used by existing services.
2Productivity
If MTC devices share CCCH resources with existing MS, then resource utilization is improved, but service quality for existing MS deteriorates
Solution Approach 1:
The patent divides CCCH resources into distinct segments: normal CCCH (groups 0-3) for existing mobile stations and MTC CCCH (groups 4-7) for MTC devices. This segmentation ensures that MTC devices can utilize additional resources (improving resource utilization) while existing MS continue to access their dedicated resources without interference (maintaining service quality).
Solution Approach 2:
The patent introduces a new intermediary layer (MTC-specific CCCH groups 4-7) that mediates between MTC devices and the network. This intermediary allows MTC traffic to be handled separately, preventing it from directly impacting the service quality of existing MS while still enabling efficient resource utilization for MTC communications.
3Device complexity
If MTC devices use existing CCCH configuration, then system complexity is reduced, but congestion control capability is insufficient
Solution Approach 1:
The patent extends the existing CCCH group structure by introducing MTC-specific groups (groups 4-7) while maintaining compatibility with the original groups (0-3). This segmentation approach allows the system to handle MTC congestion control separately without redesigning the entire CCCH configuration, thus maintaining low system complexity while improving congestion control capability.
Data Source
AI summary
The MTC device receives common control channel (CCCH) configuration information for CCCH configuration of a normal terminal and the MTC CCCH configuration information for CCCH configuration of the MTC device from a base station, selects one MTC CCCH group from a set of the MTC CCCH groups on the basis of the CCCH configuration information and the MTC CCCH configuration information, and transmits or receives data through an the MTC CCCH to which the selected the MTC CCCH group belongs.
